Casey Donovan reveals she found the man whose photos were used to catfish her

Casey Donovan has shared more details about the time she was catfished by a friend for six years.

The 31-year-old former Australian Idol winner appeared on KIIS 1065's Kyle & Jackie O Show this morning and revealed she managed to track down the man whose photos had been used to trick her into a fake relationship.

"I had pictures," Donovan said. "It was all in '04, so we still had the Nokias that you got your little pixelated pictures with. You've gotta squint for it."

Host Jackie 'O' Henderson asked what the guy looked like.

"He was bald, he had a six-pack, he had the sexy V that goes… anyway," Donovan described. "He was just a really attractive looking guy. At that point I was 16 going, 'What the hell are you doing talking to me?' I would get new photos every now and again, and he had a Myspace."

In the end, Donovan managed to find the mystery man on Instagram. She also learned a few interesting things about him: "I found out that he had… I think he had a foot fetish," she shared. "He lives in the States, and I've got no idea how she got hold of [his pictures]."

She sent him a message to say, "This is weird but I was in love with you for six years." He read the message but didn't get back to her.

Donovan has been open about her catfishing ordeal before, which is why she's also the perfect host for the upcoming local version of the MTV series Catfish.

In her memoir Big Beautiful & Sexier, the musician revealed she had been catfished by her best friend, Olga, and detailed the moment she realised her six-year relationship with a man named 'Campbell' had been a hoax.

After performing an emotional rendition of '(You Make Me Feel Like) A Natural Woman,' Donovan recalled that she broke down to her manager, Jason Williams, confessing that "[she'd] never seen" her ex-fiancé, 'Campbell'.

"My stomach turned. I felt sick," recounted the singer of the moment she told him.

In the same interview with Sandilands and Henderson, Donovan talked about how she'd had sex with Olga at Campbell's insistence.

She agreed to the sexual acts because 'Campbell' had promised they would all eventually have a threesome.

Previously, on Andrew Denton's Interview, Donovan admitted that sleeping with Olga was her first sexual experience.
